Allergic to vibrations?

Vibratory urticarial is a ultra rare genetic condition that cause people to break out in hives if their skin is vigorously vibrated or rubbed. In fact, even drying yourself with a towel can cause hives, make your face flush, give you headaches, or produce the sensation of a metallic taste. According to a new study published this week, researchers found a mutation in a gene called ADGRE2 that codes for a receptor protein found on the surface of mast cells - immune cells in the skin that dump out inflammatory molecules such as histamines that increase blood flow to an area and can cause hives. The researchers observed that shaking mast cells in a dish breaks apart two subunits of this receptor protein, which prompts histamine release. In p ...

Schizophrenia may boil down to a specific gene, scientists find
|
view preview
A landmark study, based on genetic analysis of nearly 65,000 people, has revealed that a person's risk of schizophrenia is increased if they inherit specific variants in a gene related to "synaptic pruning" - the elimination of connections between neurons. The findings represent the first time that the origin of this devastating psychiatric disease has been causally linked to specific gene variants and a biological process. They also help explain decades-old observations: synaptic pruning is particularly active during adolescence, which is the typical period of onset for schizophrenia symptoms, and brains of schizophrenic patients tend to show fewer connections between neurons. The gene, called component 4 (C4), plays a well-known role in t ...

I swear that thing was looking at me

Pareidolia is a phenomenon that allows us to "see" faces and other objects in completely unrelated objects and settings. Carl Sagan theorized that this provided an evolutionary advantage, as it allows humans to better recognize each other, even under poor visual circumstances. The important thing to remember is that even though these images may seem significant and life-changing, they aren't. It's all just a really fun figment of your imagination.

A human confused as an alien
|
view preview
This bizarre looking thing is "Ata the humanoid", a mummified corpse found in the Atacama Desert ten years ago. It's strange appearance led to many calling it an "alien", claiming it as proof that extraterrestrials have visited Earth. Well, it's finally been submitted to a battery of tests and the results show it to be fully human. DNA analysis has even managed to pinpoint the location and nationality of its mother. The results do suggest that it was once alive and human, not a hoax, and so asks more questions than they answer. The bone analysis suggests that this is not a fetus, but a child between the ages of 6-8. The specimen has just ten ribs (as opposed to 12), is just six inches long and has severe facial deformities. These symptoms do ...
